Chhattisgarh

Pt. Ravishankar Shukla University is Chhattisgarh's largest and oldest institution of higher education, founded in 1964, and named after the first chief minister of erstwhile Madhya Pradesh. The University has a sprawling campus in the western part of the capital of Chhattisgarh, Raipur. The campus of University is spread in 207 acres of land. There are Twenty-Nine teaching departments in the University. Out of which six departments buildings have been constructed recently.

National Institute of Malaria Research (NIMR) was established in 1977 as 'Malaria Research Centre', which was renamed as 'National Institute of Malaria Research' in November 2005. NIMR is one of the institutes of the Indian Council of Medical Research (an autonomous body under Department of Health Research, Ministry of Health & Family Welfare, Govt. of India).

Abstract
Clopidogrel bisulfate is an inhibitor of adenosine diphosphate (ADP)-induced platelet aggregation acting by direct inhibition of ADP binding to its receptor and of the subsequent ADP-mediated activation of the glycoprotein GPIIb/IIIa complex. Objective of the present study is to develop a simple, sensitive, accurate, precise and rapid derivative spectrophotometric method for the estimation of clopidogrel in pure form. For the estimation of clopidogrel, solvent system employed was 0.1 N HCl and wavelength of detection (λ_det) was 284.3 nm for fourth order derivative spectroscopy. The linearity was obtained in the range 42 – 336 µg/ml. The limit of detection is 6.7 µg/ml and limit of quantification was fund to be 20.4 µg/ml. Obtained results showed that there is minimum intra day and inter day variation. The developed method was validated and recovery studies were also carried out. Sample recovery using the above method was in good agreement with their respective labeled claim, thus suggesting the validity of the method and non-interference of formulation excipients in the estimation. Fourth order derivative spectroscopic method is simple, rapid and reproducible and further it can be used for the analysis.

Abstract:
A simple, rapid and precise and accurate RP-HPLC method was developed for the estimation of candesartan. The method involves a simple technique using Irbesartan as internal standard. HPLC separation was achieved using C18 Intersil column (256 x 4.6 id) with an isocratic mobile phase composed of selected methanol: 10 mM Phosphate buffer [75:25 % v/v. pH 3.0] at a flow rate of 1.0 mL/min with UV detection was performed at 256 nm. The retention time of candesartan and internal standard was found to be 1.96 and 3.33 min respectively. The assay was validated for the parameters like accuracy, precision, robustness and system suitability parameters. The method was validated over a linear test concentration range of 80 - 120%. The recovery of the method was in between 99.0 - 101.0%. The proposed method was found to be accurate, precise, selective and rapid and it can be useful in the routine analysis for the determination of candesartan cilexetil in pharmaceutical dosage form.

Abstract:
The IUPAC Name of Salmeterol is (RS)-2-(hydroxymethyl)-4-{1-hydroxy-2-[6-(4-phenylbutoxy) hexylamino]ethyl}phenol. Salmeterol is a prescription drug that is used for treating airway spasms in people with asthma or chronic obstructive pulmonary disease (COPD). By relaxing the muscles around the airways to allow more air into and out of the lungs, the medication can help prevent asthma attacks from occurring.Salmeterol comes in the form of an inhalation powder and is generally used twice a day. Present research work deals with UV spectrophotometric method for the estimation of salmeterol in pure form. For the estimation of salmeterol, solvent system employed was ethanol and wavelength of detection (λ_det) was 252 nm. The linearity was obtained in the range 6 – 14 µg/ml, with a regression coefficient, R²= 0.999. The LOD & LOQ were found to be 4.99 µg/ml and 14.24 µg/ml respectively. Obtained results showed that there is minimum intra day and inter day variation. The developed method was validated and recovery studies were also carried out. Sample recovery using the above method was in good agreement with their respective labeled claims, thus suggesting the validity of the method and non-interference of formulation excipients in the estimation.
